Abstract
A light-emitting device includes a circuit carrier board having a short side and a long side, a plurality of light-emitting units on the circuit carrier board for emitting three or more color lights, and a light-transmitting glue layer on the circuit carrier board and covering the plurality of light-emitting units. The short side is shorter than the long side. The plurality of light-emitting units include a first light-emitting unit. The first light-emitting unit has a light exit surface, a first sidewall, and a second sidewall. The first sidewall faces the short side and has a first included angle with the light exit surface, and the second sidewall faces the long side and has a second included angle with the light exit surface. The first included angle is between 85 to 95 degrees, and the second included angle is less than 85 degrees or greater than 105 degrees.
